Description

A coil winding device and method of winding an elongate member

TECHNICAL FIELD The present invention relates to a coil winding device, and in particular, but not limited to, a device for winding a fully annealed tube into a coil with minimal work hardening.

Annealing processes are commonly used in copper tubes to improve the properties of the tubes for use in products such as refrigeration units. Referring to FIG. 1, coils of a hard copper tube stored in a basket 10 are re-coiled around the axis of rotation to form coils of a plurality of layers of annealed copper 14. Before re-coiling, it is processed via an annealing line 12 to remove any work hardening. However, the process itself to re-coil the copper tube after the annealing process causes work hardening on the copper.

A first method of winding a fully annealed tube into a coil is shown in Figures 2 (a) and (2), in which a set of rollers (100) are shown, between the rollers The distance can be adjusted. The tube 102 may be wound up into coils by such rollers 100, such winding being slightly bent in the tube 102 as the tube 102 passes between the rollers 100. This is accomplished by rolling a tube 102 between the rollers 100 when the rollers 100 are arranged so that this can be caused, which is shown in FIG. 2B. The bent tube is positioned such that the bent portion of the tube 102 lies loosely on a platform 104 as more tubes 102 pass between the rollers 100, and the platform 104 is positioned. The silver tube 102 rotates about the axis 106 at a speed that corresponds to the speed at which it passes between the rollers 100. The position of one of the rollers 100 is constantly adjusted to vary the degree of bending of the tube 102, such that the tube 102 is concentric on the platform 104 as the platform 104 rotates. Concentric windings with different diameters are formed in the conventional coil.

However, such a process has a number of limitations. For example, the use of the rollers 100 negatively affects the hardness of the tube 102, which increases in proportion to the degree of bending required to obtain the diameters of each winding in the coil. Layers of coils produced using this method are loosely wound and also have inconsistent spacing between each coil. The presence of overlaps of windings of coils in different layers means that more three-dimensional space per coil is needed for packaging and transportation. In addition, since the free space between the windings of each coil allows the movement and potential bumps of the overlapping windings in the concentric coil layers, there is a high risk that each coil will be damaged during transportation.

When using such a first method of tube winding, nitrogen gas needs to be blown through the tube in an 'upstream' direction towards the apparatus performing the annealing process. This gas is used to remove oxygen from the tube while the tube is annealed to reduce the formation of impurities on the inner surface of the tube. Typically, the tube is passively coupled to a back purge system that is used to blow nitrogen gas back through the tube. In this example, the first few windings of the coil will not anneal correctly because the tube will not move at the correct speed through the anneal apparatus. As a result, the first few windings of the final coil will not comply with the specification.

A second method of winding the tube into the coil is shown in FIG. 3. This figure shows a cylindrical drum 200 in which one end of the tube 202 is secured to the point 204. The drum 200 is rotated about an axis 206 that causes the tube to be wound around the drum 200. The drum 200 is made to move along the axis 206, and the drum 200 also rotates around the axis 206 at a speed corresponding to the rotational speed of the drum 200. Each successive winding of the tube 202 is translated displaced along the axis 206 relative to the preceding winding. The windings of the different coils are wound on the drum 200, resulting in them being placed on top of each other, whereby a number of layers of coils are formed around the drum. The drum 200 has flanges 203 that can be adjusted to set the depth of the resulting coil.

This second method of winding the tube into coils has an advantage over the first method in that each of the layers of coils is wound tighter and the spacing between each coil is configured more accurately.

However, the second method has the disadvantage that significant work hardening is applied to the tube while the tube is wound into a coil. This requires that the length of the tube wound tightly by the second winding method should be annealed in an oven after the winding process. However, the maximum size of the coil is determined by the size of the annealing furnace.

Preferred embodiments of the present invention aim to solve the above disadvantages of the prior art.

According to one aspect of the invention, there is provided an apparatus for winding an elongate member into a coil, the apparatus comprising:

At least one first body portion adapted to rotate about a first axis;

Fixing means for securing a portion of the elongate member to at least one said first body portion; And

Force application means for applying a force to the elongate member;

The force includes a first force component and a second force component acting in each of the first and second directions perpendicular to each other, wherein the first direction and Limiting movement in a direction parallel to the second direction, the first force component acts toward the first body portion to which the elongate member is fixed.

One coil while the coil is being wound by applying a force having a first force component and a second force component perpendicular to the tube while the tube is wound so as to be a plurality of coils stacked on top of another coil. It is possible for each individual winding in the body to be held in place. By applying a force in the direction of the winding portion preceding each individual winding portion in the coil while the coil is being wound, the advantage is provided that the coil is wound more closely. By applying downward force to each winding in the coil while the coil is being wound, the windings in each of the layers of coils stacked on top of the other coil layer do not overlap with the windings of the coils in the different layers. This provides the advantage of minimizing the cubic space per coil required for packaging and transportation, and also minimizes the free space between the windings of each coil, thereby overlapping in otherwise concentric coil layers. Movement and potential collisions of the windings are made possible to reduce the possibility of damage that can be inflicted on the individual coils during transportation.

The winding device of the present invention provides the advantages described above while at the same time minimizing work hardening on the tube while the tube is being wound.

In a preferred embodiment, the means for applying the force comprises a second body portion from which the plurality of bristles extend.

Bristle offers the advantage of applying two orthogonal force components to the tube while the tube is wound, to provide the advantages described above.

In another preferred embodiment, at least one of the first body portion or the second body portion forms a planar surface.

This has the advantage that the tube provides a surface on which it can be easily wound up and released and also has the advantage that the device used to transport such wound tube is simplified.

In another preferred embodiment, at least one of the first body portion or the second body portion is adapted to move along the first axis.

This offers the advantage of quickly winding up a plurality of coil layers and also minimizes the length of bristle required to provide other advantages of the present invention.

In a preferred embodiment, the elongate member is wound to be a coil, from the inner side of the first body portion adjacent the center of the first body portion to the outer side of the first body portion adjacent the edge of the first body.

In another preferred embodiment, the elongate member is wound to be a coil from the outer side of the first body portion adjacent the edge of the first body portion to the inner side of the first body portion adjacent the center of the first body portion.

In another preferred embodiment, the elongate member is an elongate tube.

In a preferred embodiment, the coil winding device further comprises a guide, wherein the elongate member extends from the guide and engages with the device.

In another preferred embodiment, the first body portion is adapted to move relative to the guide portion.

This provides the advantage of using the apparatus of the present invention to more accurately control the diameter of each of the windings in the coil so wound.

In another preferred embodiment, the coil winding apparatus further includes an annealing portion for annealing at least a portion of the elongate member before the elongated member is wound into a coil.

This provides the advantage of minimizing the degree of work hardening of the coil once the coil is wound up. Furthermore, by annealing the tube before the tube is wound into the coil, it is possible for the individual parts of the tube to be annealed separately, rather than annealed at once after the entire tube has been wound into the coil. This provides the advantage that the size of the furnace used to anneal the tube to be wound using the device of the invention is reduced.

According to one aspect of the invention there is provided a method of winding a long member to be a coil, the method comprising:

Securing a portion of the elongate member to the first body portion;

In a preferred method, the winding method of the elongate member further comprises moving the first body portion and the force application means relative to each other along the first axis.

In another preferred method, the elongate member is wound to be a coil from the inner side of the first body portion adjacent to the center of the first body portion to the outer side of the first body portion adjacent to the edge of the first body portion.

In another preferred method, the elongate member is wound to be a coil from the outer side of the first body portion adjacent to the edge of the first body portion to the inner side of the first body portion adjacent to the center of the first body portion.

4A, 4B, and 4C, a winding device 300 is provided to wind an elongate member such as, for example, a metal tube 303 into a coil. The winding device 300 includes a first body portion 302 and a second body portion 304, both of which preferably have a disc shape. The first body portion 302 is adapted to rotate about the first axis 306. The winding device 300 has fixing means for fixing a portion of the tube 303 extending from the guide member 305 to the first body portion 302. The metal tube passes through the guide member 305 and is connected to a purging unit in the first body 302 using an automatic clamping system (see FIG. 7). The second body portion 304 includes a plurality of bristle 308 and cylindrical form member member 309 extending in the direction of the first body portion 302 from the second body portion 304. Equipped. The bristle 308 and the former member 309 preferably have a length that is approximately twice the diameter of the tube 303 wound into the coil by the apparatus 300. The former member 309 has a diameter through which the tube can be bent without causing an unacceptable degree of work hardening to the tube. Such a diameter can be approximately 600-700 mm, which is 50 to 60 times the tube diameter.

The first body portion 302 has a shaft (B) to allow the bristle 308 and the former member 309 to contact the tube 303 such that the bristle 308 is bent around the tube 303. 306 is adapted to move along. Each bristle 308 bent by the tube 303 exerts a force 310 on the tube 303. The bristle 308 bent by the tube 303 as shown in FIG. 5 exerts a force on the tube 303 along the direction 310. This force may be decomposed into right angle first and second force components acting in a first direction 312 and a second direction 314 forming a right angle. Therefore, such components of the force acting on the tube 303 are such that the first direction 312 and the second direction 314 in which the tube 303 acts respectively the first force component and the second force component of the force 310. Restrict movement in the direction parallel to.

Hereinafter, a process of winding the annealed tube with the coil by the winding device 300 will be described. First, an end portion of the elongated tube 303 extending from the guide member 305 is fixedly attached to the first body portion 302 adjacent to the center of the first body portion 302 so that the tube is the second body. When it comes into contact with the shaper member 309 of the part 304, it can be wound around it.

Next, the former member 309 and the bristle 308 of the second body portion 304 come into contact with the tube 303 so that the bristle 308 is bent around as shown in FIG. 5. . The first body portion 302 is then rotated about the axis 306. At the same time, both the first body portion 302 and the second body portion 304 are second axes perpendicular to the first axis 306 at a speed corresponding to the speed at which the first body portion 302 rotates. Moved along 307 to cause the tube 303 to be wound into the first coil, the first coil comprising a plurality of windings having increasing diameters, the innermost winding being the former member 309. ), And each successive winding is gradually further from the center of the first body portion 302.

When the first coil in contact with the first body portion 302 is fully wound, i.e., when the windings are wound from the former member 309 to the edge of the first body portion 302, the first body portion of the one tube Away from the second body by a distance of the diameter. Then, both the first body portion 302 and the second body portion 304 begin to move back along the second axis 307 at the same speed that was moved when winding the first coil. This causes the tube 303 to be wound onto the second coil on top of the first coil. The second coil consists of the same number of windings as the number of windings of the first coil, with each winding of the second coil being on top of the corresponding winding in the first coil. During winding of the second coil, the windings in the second coil are reduced in diameter as the first body portion 302 and the second body portion 304 and the shaft 306 move back toward their original position. It is wound up, and each winding portion is gradually closer to the center of the first body portion 302, and the innermost winding portion of the winding portion comes into contact with the creator member 309 of the second body portion.

When the second coil is wound, the first body portion 302 is moved away from the second body portion 304 along the axis 306 by the same dimension as the diameter of the tube 303 being wound. Then, a third coil is wound on the second coil, the diameters of the windings gradually increase, the innermost winding portion contacts the former member, and the outermost winding portion is adjacent to the edge of the first body portion. do. The first body portion 302 is then moved away from the second body portion 304 along the axis 306 by the same dimension as the diameter of the tube 303 being wound. Then, a fourth coil having windings having a gradually decreasing diameter is wound on the third coil, of which the innermost winding portion contacts the former member member 309. This winding process is repeated, until the required number of coil layers are stacked up, the first body portion 302 is dimensioned by the same dimensions as the diameter of the tube 303 being wound after the winding of each successive coil. Move along axis 306 relative to second body portion 304.

When the tube 303 is wound with the required number of coil layers, the tube 303 is removed from the guide member 305 and the former member 309 and bristle 308 of the second body portion 304. Are separated from the coils wound around the first body portion 302, and the first body portion 302 is subsequently separated from the device 300.

Bristle 308 for a coil wound from an inner portion of the first body portion 302 adjacent to the center of the first body portion 302 to an outer portion of the first body portion 302 adjacent to the edge of the first body portion The influence of these is shown in FIG. 6A. Bristle 308, which is bent by tube 303 wound to be a coil, exerts a two component force on tube 303. One component of the force acts in the direction toward the first body 302 relative to the tube 303, minimizing the distance between the different coil layers within the pile of coil layers produced by the device 300. Let's do it. In addition, the second component of the force acts on the tube 303 along a direction perpendicular to the first body portion 302 towards the center of the first body portion, as it is wound around the windings in each coil. The windings are pushed together so that the coils are wound more tightly.

The situation corresponding to the situation shown in FIG. 6A, that is, the inner side of the first body portion 302 adjacent to the center of the first body portion from the outer portion of the first body portion 302 adjacent to the edge of the first body portion 302. The effect of the bristle 308 on the coil wound up to the part is shown in FIG. 6B. Bristle 308, which is bent by tube 303 wound to be a coil, exerts a two component force on tube 303. One component of the force acts in the direction toward the first body 302 relative to the tube 303, reducing the distance between the different coil layers in the pile of coil layers produced by the device 300. In addition, the second component of the force acts on the tube 303 along a direction perpendicular to the first body portion 302 away from the center of the first body portion, as it is wound around the windings in each coil. The windings are pushed together so that the coils are wound more tightly.

Tube 303 passes through an annealing device (not shown) before being wound into a coil through the use of device 300. For this reason, while the winding apparatus 300 of this invention is in use, an inert gas, such as nitrogen, is blown through the tube 303 by using a reverse purification system. In the winding device 300, the tube 303 is automatically connected to the reverse purification system using an automatic clamping system (see FIG. 7). In this example, if tube 303 is to be stopped because the winding device 300 is not annealed upstream to the specification, it is in a system between the winding device 300 and the annealing device and the specification Mismatched tubes will be removed and discarded from the system so that it will not be part of the final coil.

Hereinafter, the operation of the automatic clamping system shown in FIG. 7 will be described. The clamping system 317 is mounted to the first body 302 and has a chamber 318 through which an inert gas is blown. The tube 303 wound by the winding device 300 must first be clamped in place using the clamp 316 before being wound, which clamping allows the inert gas to be blown into the tube 303. In order to extend the end of the tube 303 into the chamber 318. To this end, the tube 303 emerging from the guide 305 enters the clamping system 317 by passing through the guide and clamp actuator 319 and the clamping element 316, and The end of the tube extends in chamber 318. Guide and clamp actuator 319 is moved towards clamping element 316, which clamps and seals tube 303 before nitrogen back purging is initiated. The tube remains tight throughout the winding process described above, allowing the complete length of the tube 303 to be continuously back-purged. At the end of the winding process, the guide and clamp actuator 319 is moved away from the clamping element 316 which releases the tube 303.

To those skilled in the art, the above embodiments have been described by way of example only, and not in a limiting sense, without departing from the scope of the invention as defined by the appended claims. It will be understood that variations and modifications are possible. For example, the winding device 300 can be used to wind a long member made of plastic, for example, not a long member made of metal, with a coil. The winding device 300 may wind the coil by rotating in the counterclockwise direction as well as in the clockwise direction. The present invention can be adapted to be able to wind a tube around a cylindrical body with a coil, while retaining all of the advantages described above. Such adaptation is shown in FIG. 8, wherein parts similar to those in FIGS. 4A-4C are indicated with reference numerals added 100.
